than the maximum power capacity
provided by the vehicle.
- Electrical products that require
high power during initial
operation.
- Measuring devices that need to
process accurate data.
- Electric products sensitive to
inverter type AC power supply
(Inverter: A device that converts
DC power into AC power)
• Do not use products that require
a continuous power supply,
such as medical equipment. The
power supply may be interrupted
depending on the vehicle’s
condition.
• Only use home appliances under 16
ampere.
• Put the power plug fully and use
the qualified plug that meets the
standard. If you use worn, corroded
or broken plug or improper plug, it
might be a cause of malfunction. •
Use the power plug with ground
connection.
• Do not use high power home
appliances such as air conditioner,
washing machine or dryer.
• Do not hang the home appliances on
to the wire.
• For various devices connected to

If you pull the cable itself (without
using the handle), the internal wires
may disconnect or get damaged. This
may lead to electric shock or fire.
CAUTION
• Always keep the charging connector
and charging plug in clean and
dry condition. Be sure to keep the
charging cable in a condition where
there is no water or moisture.
• Be sure to use only certified electric
vehicle charger. Using uncertified
charger may cause the damage to
the vehicle.
• Before charging the battery, turn the
vehicle OFF.
• When the vehicle is switched OFF
while charging, the cooling fan
inside the motor compartment may
automatically operate. Do not touch
the cooling fan while charging.
• Be careful not to drop the charging

6. Check if the charging indicator light (
) of the high voltage battery in
the instrument cluster is turned ON.
Charging is not active when the
charging indicator light (
) is OFF.
When the charging connector is not
connected properly, reconnect the
charging cable to charge it again.
During cold weather, DC charging
may not be available to prevent high
voltage battery degradation.
Information
To control the temperature of the high voltage battery while charging, the
air conditioner is used to cool down the battery which may generate noise
from operation of the air conditioner
compressor and cooling fan.
Also, the air conditioner’s performance
may be degraded during summer due to
operation of the cooling system for the
high voltage battery.
Information
Even though charging is possible with
the Start/Stop button in the ON/START
position, for you safety, start charging when the Start/Stop button is in the
OFF position and the vehicle shifted to P
(Park). After charging has started, you can use electrical components such as the
radio by pressing the Start/Stop button to
the ACC or ON position.
During charging, the gear cannot be
shifted from P (Park) to any other gear.
ONE1Q011059E
7. After charging has started, the
estimated charging time is displayed
on the instrument cluster for about 1
minute.
If you open the driver seat door while
charging, the estimated charging time
is also displayed on the instrument
cluster for about 1 minute.
Information
• Depending on the condition and
durability of the high voltage battery,
charger specifications, and ambient
temperature, the time required for
charging the battery may vary.
• In rare cases, you might hear high
frequency noise (very little beep sound)
outside the car when charging with
400V fast charger that is deteriorated
or has long communication delay.
The high frequency noise can be
generated only when the car tries to
reduce its own electromagnetic waves to keep fast charging as possible.
So there is no need to worry about this little noise, because it is the intentional
operation of the car that does not
affect any charging performance or the vehicle itself at all.

[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : PTC & Inner condenser
The cabin air filter is installed behind the
front trunk. It filters the dust or other
pollutants that enter the vehicle through
the heating and air conditioning system.
Have the cabin air filter replaced by an
authorized HYUNDAI dealer according to
the maintenance schedule. If the vehicle
is being driven in severe conditions such
as dusty or rough roads, more frequent
cabin air filter inspections and changes
are required.
If the air flow rate suddenly decreases,
have the system inspected at an
authorized HYUNDAI dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning
is reduced. Overfilling also reduces the
performance of the air conditixoning
system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.
NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
NOTICE
The refrigerant system should only
be serviced by trained and certified
technicians to insure proper and safe
operation.
The refrigerant system should be
serviced in a well-ventilated place.
The air conditioning evaporator (cooling
coil) shall never be repaired or replaced
with one removed from a used or
salvaged vehicle and new replacement
MAC evaporators shall be certified
(and labeled) as meeting SAE Standard J2842.

Trailer
Your vehicle will need service more
often when you regularly pull a trailer.
Important items to pay particular
attention to include reduction gear fluid,
axle lubricant and cooling system fluid.
Brake condition is another important
item to frequently check. If you’re
trailering, it’s a good idea to review these
items before you start your trip. Don’t
forget to also maintain your trailer and
hitch. Follow the maintenance schedule
that accompanied your trailer and check
it periodically. Preferably, conduct the
check at the start of each day’s driving.
Most importantly, all hitch nuts and bolts
should be tight.
